Comprehensive evaluation method for outage schemes considering the entire construction process

To address the dynamic changes in power system operating conditions during engineering construction and the difficulty in quantitatively comparing different outage schemes, a comprehensive evaluation method for outage schemes considering the entire construction process is proposed. An evaluation index system is established from three dimensions: power system operational reliability, scheme implementation management, and outage implementation effectiveness. The Analytic Hierarchy Process is employed to determine the weights of the evaluation indices, and a comprehensive evaluation model is subsequently established to achieve the quantitative comparison and optimal selection of different outage schemes. A 220kV Substation A renovation project in Jiangsu is taken as a case study, where three alternative schemes are evaluated. The corresponding evaluation scores are 0.675, 0.343, and 0.557, respectively. Scheme 1 obtains the highest score, which is consistent with the scheme recommended in the actual engineering project, thereby verifying the effectiveness of the proposed method.
